A port of the browser's btoa function.
Uses Buffer to emulate the exact functionality of the browser's btoa (except that it supports some unicode that the browser may not).
It turns binary data to base64-encoded ascii.
(function () {
  "use strict";

  var btoa = require('btoa');
  var bin = "Hello, 世界";
  var b64 = btoa(bin);

  console.log(b64); // "SGVsbG8sIBZM"

Note: Unicode may or may not be handled incorrectly. This module is intended to provide exact compatibility with the browser.
